Definitions

  • the present invention relates to tires. More particularly, she relates to a tire, in particular for a two-wheel type vehicle, having an anti-vibration means.
  • the manufacturers of such vehicles are therefore implementing to tackle the problem of vibrations.
  • Manufacturers of various bodies of the vehicle are not left behind since everyone can contribute to a greater or lesser extent to mitigate or dampen vibrations induced, or even better, eliminate them at source.
  • the manufacturers of pneumatics can play a decisive role with regard to due to rolling and imperfections of the road.
  • the front tire can constitute a key element in this respect.
  • the reinforcement of tire carcasses is at present constituted by one or more layers (conventionally referred to as "carcass plies" of by the manufacturing process in the form of semi-finished products in the form of tablecloths), provided with wire reinforcements that can be radial. Anchoring or maintenance of these sheets or reinforcements is carried out, traditionally by a flipping a portion of web around a rod disposed in the bead of the tire.
  • EP 0 582 196 describes a way of arranging a carcass-type reinforcement structure in the beads, having disposed adjacent to said reinforcing structure circumferential filaments, all of which is embedded in a rubber mix anchoring or bonding, preferably with a high modulus of elasticity. Many Arrangements are provided in this document. This document is also reference to tires manufactured without the aid of semi-finished products under form of tablecloths.
  • the wires of the various reinforcement structures are applied directly to adjacent layers of rubber mixes, the whole being applied in successive layers on a core having a shape to obtain directly a profile similar to the final profile of the pneumatic in the process of manufacture. So, in this case, rather than 'tablecloths carcasses “in the classical sense, we find more specifically" reinforcements of carcass type ". This denomination, which actually refers to the reinforcements of one or the other type will be used in this document.
  • EP 0 976 536 also describes a way of arranging a structure reinforcement of carcass type in the beads, having adjacent said reinforcing structure of the circumferential filaments, all of which is embedded in a rubber mix of anchoring or bonding.
  • the present invention therefore aims at providing a tire, in particular a tire for a two-wheel type front wheel, with improved performance with respect to vibration behavior, particularly shimmy.
  • the transition zone from which the radius defined by the meridian profile of the tread changes abruptly to interrupt the course of the tread, is a major feature of the tire for two-wheeled vehicle. No point of a conventional tire profile for four-wheeled vehicle or more does not compare to the latter.
  • This last type of pneumatic by the design of the vehicles that it equips, has in general of a substantially flat tread, or of small radius.
  • the contact area between the ground and the tire is substantially narrow with respect to the width of the tread. This zone is also mobile along the tread profile, depending on the the inclination of the motorcycle. This is all the more important as the dynamic constraints strongly differ between two-wheeled vehicles and other types of vehicles. This justifies for example the presence of pneumatic different for the front wheel and the rear wheel of a significant number of motorcycles.
  • the object of the The present invention is therefore intended primarily for use on the front wheel a two-wheeled vehicle. It can also be used for the wheel back or both.
  • the anti-vibration means Depending on the material constituting the wire or wires of the winding of the anti-vibration means (eg aramid, metal, fiberglass, polyester, etc.), types of rubber mixtures in which the yarns are arranged, the density of the son and winding number, the transverse rigidity of the while maintaining substantially a certain stability of the others tire stiffnesses such as vertical and longitudinal stiffnesses.
  • the anti-vibration means allows a decoupling of the transverse stiffness by compared to other rigidities.
  • favorable results are obtained for kick-back type vibrations, waving, stability of the centrifugal profile (wear, stability), etc.
  • the anti-vibration means ensures a connection mechanical or co-operation between the lateral portion of the tread and the portion of the sidewall in which said means is disposed. It is this connection which contributes to stiffening the tire in the transverse direction. We in this way acts directly on the amplitude and frequency of the shimmy.
  • said anti-vibration means comprises at least one thread substantially circumferentially aligned, or a series of aligned and distributed wires circumferentially.
  • the angle of the wires is substantially 0 ° relative to the circumferential direction.
  • the wires thus form alignments can take a multiplicity of forms.
  • Wire alignments can also be arranged and manufactured in many ways.
  • a alignment may advantageously consist of a single wound wire (substantially zero degrees) spiral over several turns, preferably from the smallest diameter to the largest diameter. It can also be constituted several concentric threads laid one inside the other, forming a superposition of gradually increasing diameter rings. It is not necessary to add a mixture of rubber to ensure the impregnation of the wire or circumferential windings of wire.
  • the present invention also provides the use of an anti-vibration means substantially peripheral to decrease the generation of vibration-type shimmy in a two-wheeled vehicle tire having at least a carcass-type reinforcement structure anchored on each side of the tire in a bead whose base is intended to be mounted on a rim seat, each bead extending radially outwardly by a flank, the flanks joining radially outwardly a tread whose ratio Ht / Wt is greater than 0.15, the reinforcing structure extending circumferentially from the beads to said flanks, said tire also having a transition zone substantially corresponding to the passing from the lateral portion of the tread to the sidewall, said anti-vibration means being circumferentially disposed in said transition zone and extending radially on the one hand substantially radially outwards towards the top and secondly substantially radially internally in the sidewall.
  • the anti-vibration means comprises advantageously at least one alignment of substantially circumferential son. Moreover, this anti-vibration means advantageously provides a connection between the lateral portion of the tread and the portion of the sidewall wherein said means is disposed. It is this mechanical connection that helps to stiffen the tire in the transverse direction. We act in this way directly on the amplitude and frequency of the shimmy.
  • Such anti-vibration means is advantageously used in a tire wherein the carcass-type reinforcement structure is anchored in the bead thanks to at least one arrangement of anchoring threads along a path circumferentially disposed substantially adjacent to said structure.
  • the anti-vibration means can also be used with a conventional tire, comprising a bead wire around which a carcass is returned, as shown for example in Figure 4.
  • the anti-vibration means is advantageously constituted by at least one aligned thread substantially circumferentially or a series of son aligned and distributed circumferentially.

  • characteristics of the wire one understands for example its dimensions, its composition, its characteristics and mechanical properties (in particular the module or toughness), its characteristics and chemical properties, etc.
  • the rows of wires are arranged so as to be contact with at least one high modulus rubber compound.
  • the alignments are surrounded by a first side by a first mixture and on the other side by a second mixture.
